Ionic compounds break apart into the ions that make them up, a process called dissociation, while covalent compounds only break into the molecules, not the individual atoms.ttp://socratic.org/chemistry.

This is a list of the solubility rules for ionic solids in water. Solubility is a result of an interaction between polar water molecules and the ions which make up a crystal. Two forces determine the extent to which solution will occur: Force of attraction between H2O molecules and the ions of the solid. This force tends to bring ions into solution. If this is the predominant factor, then the compound may be highly soluble in water. Force of attraction between oppositely charged ions. This force tends to keep the ions in the solid state.
